Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, an embodiment of this application discloses a multi-head composite pressure holding device, including a mounting plate 1. Multiple sets of pressure holding head assemblies 2 are horizontally arranged on one side of the mounting plate 1, and multiple sets of lifting drive mechanisms for driving the pressure holding head assemblies to perform lifting and lowering movements are arranged on the other side of the mounting plate 1. The lifting drive mechanisms correspond one-to-one with the pressure holding head assemblies.

[0029] The pressure holding head assembly includes a pressure head mounting bracket, and multiple pressure holding heads are provided at the bottom of the pressure head mounting bracket. The positions of the multiple pressure holding heads correspond to the pressure holding positions of the product.

[0030] In practice, multiple products are located below multiple sets of pressure-holding head assemblies 2. The lifting drive mechanism is activated, which drives the corresponding pressure-holding head assemblies to descend until the multiple pressure-holding heads contact the pressure-holding positions of the corresponding products. At this point, the lifting drive mechanism stops working and performs the pressure-holding operation on the products.

[0031] The above-described structure not only improves the convenience of pressure holding operations but also ensures the stability and accuracy of the pressure holding process. In practical applications, operators only need to adjust the position and height of each pressure holding head component according to the specific pressure holding requirements of the product to achieve simultaneous pressure holding at different positions and heights, greatly improving work efficiency.

[0032] In this embodiment, the pressure head mounting frame includes a horizontal plate 201 and a vertical plate 202, which are connected to form an L-shaped structure. A spline nut 202 is provided inside the horizontal plate 201, and a spline rod 204 is fitted inside the spline nut 202. An upper mounting block 205 is installed on the upper end of the spline rod 204, and a lower mounting block 206 is installed on the lower end of the spline rod 204. The lower mounting block 206 is fixedly connected to the pressure head, and multiple weights 207 are installed on the upper mounting block 205.

[0033] Specifically, when the lifting drive mechanism drives the pressure head mounting bracket downwards, the pressure holding head, upper mounting block 205, lower mounting block, spline rod 204, and weight 207 structure will fall downwards due to their own weight. Once the lower pressure holding head contacts the PCB board, it stops moving. At this point, the horizontal plate 201 contacts the lower mounting block 206, and all the pressure on the weight 207 is transmitted to the pressure holding head, applying pressure to the PCB board. The pressure of the pressure holding head can be adjusted by increasing or decreasing the number of weights 207, thus meeting the different pressure holding requirements of different products. Simultaneously, the cooperative design of the spline nut 202 and spline rod 204 prevents the spline rod 204 from rotating, ensuring stability and accuracy during the pressure holding process. Furthermore, this design allows the gravity of the weights 207 to act on the pressure holding head during the pressure holding operation, eliminating the need for an additional power source and reducing energy consumption and cost.

[0034] In this embodiment, the pressure holding head includes an upper pressure holding block 208 and a lower pressure holding block 209, and a pressure sensor 210 is disposed between the upper pressure holding block 208 and the lower pressure holding block 209.

[0035] Specifically, the pressure sensor 210 can monitor the pressure of the pressure holding head on the product in real time, which can help the operator to promptly identify and resolve any abnormalities that may occur during the pressure holding process, thereby further improving the pressure holding effect and product quality.

[0036] In this embodiment, a silicone pressure head 211 is provided at the bottom of the lower pressure block 209.

[0037] Specifically, the silicone pressure holding head 211 possesses excellent wear resistance and corrosion resistance, maintaining a stable pressure holding effect during prolonged use. Simultaneously, the flexibility of the silicone pressure holding head 211 reduces damage to the product, protecting its surface quality. This design not only extends the lifespan of the pressure holding head but also reduces maintenance costs.

[0038] In this embodiment, a horizontal adjustment plate 212 is provided on the side of the vertical plate 202 away from the horizontal plate 201, and a vertical guide rail 213 is provided on the horizontal adjustment plate 212. The vertical plate 202 and the vertical guide rail 213 are slidably connected by a first slider.

[0039] The mounting plate 1 is also provided with a transverse slide rail 101. The horizontal adjustment plate 212 is slidably connected to the transverse guide rail through a second slider. The horizontal adjustment plate 212 is provided with a first position fixing hole and a second position fixing hole respectively. The mounting plate 1 is provided with a third position fixing hole and a fourth position fixing hole respectively that cooperate with the first position fixing hole and the second position fixing hole, so that the horizontal adjustment plate 212 and the mounting plate 1 are fixedly connected by bolts.

[0040] Specifically, when the first position fixing hole and the third position fixing hole are aligned, the horizontal adjustment plate 212 is located at the first position, and when the second position fixing hole and the fourth position fixing hole are aligned, the horizontal adjustment plate 212 is located at the second position.

[0041] Specifically, the operator can fine-tune the horizontal position of the pressure head mounting bracket by adjusting the position of the horizontal adjusting plate 212 on the transverse guide rail, thereby ensuring accurate alignment of the pressure holding head and improving the pressure holding effect. After adjustment, the operator can use bolts to fix the horizontal adjusting plate 212 to the mounting plate 1 to ensure the stability of the pressure head mounting bracket during the pressure holding process. This design not only improves the flexibility and applicability of the device but also reduces the difficulty of operation, thus ensuring the accuracy of pressure holding.

[0042] In this embodiment, a fixing plate 214 is also provided at the upper end of the horizontal adjustment plate 212. One end of the fixing plate 214 is fixedly connected to the horizontal adjustment plate 212, and the other end of the fixing plate 214 is provided with a first waist-shaped groove 215. The top of the mounting plate 1 is provided with bolt holes that cooperate with the first waist-shaped groove 215, so that the fixing plate 214 and the mounting plate 1 are fixedly connected by bolts.

[0043] Specifically, the operator can fine-tune the horizontal position of the pressure head mounting bracket by adjusting the position of the horizontal adjustment plate 212 on the transverse guide rail. After adjustment, the operator can use bolts to fix the fixing plate 214 and the mounting plate 1 to ensure the stability of the pressure head mounting bracket during pressure holding. This design not only improves the flexibility and applicability of the device, but also makes the adjustment process more convenient and quick for the operator, further improving work efficiency.

[0044] In this embodiment, the lifting drive mechanism includes a drive cylinder 3, the drive end of the drive cylinder 3 is connected to a lifting block 4, and the other end of the lifting block is fixedly connected to the pressure head mounting bracket.

[0045] Specifically, when the drive cylinder 3 is working, its drive end will push the lifting block 4 to move up and down. Since the lifting block 4 is fixedly connected to the pressure head mounting frame, the lifting movement of the lifting block 4 will drive the pressure head mounting frame and the pressure holding head assembly on it to move up and down synchronously, thereby realizing the pressure holding operation of the product.

[0046] In this embodiment, the lifting block 4 is provided with a second waist-shaped groove 401 at the driving end of the driving cylinder 3, and the lifting block 4 is fixedly connected to the driving end of the driving cylinder by bolts.

[0047] Specifically, when the horizontal adjustment plate 212 is finely adjusted laterally, the position of the lifting block 4 will also change synchronously. At this time, due to the setting of the second waist-shaped groove 401, it can adapt to the slight changes in the position of the lifting block 4, ensuring that the lifting block 4 and the drive end of the drive cylinder 3 always maintain a stable connection relationship.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
